The terminology used by different organizations working
on similar or overlapping technical areas of standardization
has complicated attempts to co-ordinate work between different groups.
The same terms are often used, with different meanings by multiple organizations.
Readers are warned to verify the definitions before assuming a common understanding
of the terms. Specific appendices have been included in ITU-T Recommendations G.7713
.x to assist the reader in mapping signalling protocol terminology used in those document
to the similar terms used in other well know references.
